LAMP.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed March 5, 1906. Serial No. 304,369.

To all whom it may concern:

Be it known that I, WILLIAM SPENcER RYAN, a citizen of the UnitedStates, and a resident of Viola, in the county of Mercer and State ofIllinois, have invented a new and Improved Lamp, of which the followingis a full, clear, and exact description.

This invention is an improvement in lamps, and has for an object, amongothers, to provide a lamp which has its supply of illuminating oil orgasolene ever ready, thus dispensing'with the work of daily refilling.

It is especially designed to have the oil tank or reservoir in the formof a street lamp post, which connects with a small feed tank forsupplying the lamp for a predetermined length of time. By thisconstruction the feed tank can be filled from the reservoir to feed thelamp for any desirable eriod, and when the fuel is consumed in the feedtank, the lamp will automatically go out.

Reference is to be had to the accompanying drawing, and to thecharacters of reference thereon, the figure representing a partlysectional side elevation of a lamp post of novel construction, havingother details of the invention mounted thereon.

The numeral 1 indicates a framework or stand for a lamp post, made up oflongitudinal bars 2 equally spaced apart and secured to a base 3 mountedon legs 4. At the upper end of the bars 2 is a ring 5 integraltherewith, for holding the bars securely together. Carried in theframework 1 and resting on the base 3, is a large tank or reservoir 6,having a pressure gage 7, and a hooked arm 8 for suspending a lamp 9. Atone side of the reservoir 6, mounted on a bracket 6 is a pump casing 10,for containing a hand pump 11, of ordinary construction, secured to thebottom of the casing and having a tube 12, for connecting it through avalve 12, to the reservoir. At the upper end of thecasing 10 a lid 13 ishinged, and held in closed position by a catch 14 when the pump is notin use.

Suspended by means of a hook 15 is a small feed tank 16, having a glassgage 17, connected by a pipe or hollow wire 18, with a nozzle 19 througha cock 20. The feed tank has on its upper face a small stop valve 16which can be opened or closed according to whether a gravity or acombined gravity and air pressure feed, is desired. Adjacent to theouter end of the nozzle 19 is a funnel or enlarged pipe 21, attached toa curved pipe 22 leading to the lamp. The nozzle 19 is as shown, passedover the top of the lamp, in order that the gasolene or oil may beconverted into a gas before the combustion takes place.

Projecting into the top of the tank 16, and preferably following aroundthe hook mem ber 8 down through a cook 24 and reservoir 6, and endingslightly below the bottom of the reservoir in a pipe 25, is a pipe orhollow wire 23. The pipe 25 is provided with a cook 26 adjacent to thereservoir, and may pass underground, as shown, and terminate at theother end in a small pipe or hollow wire 27, for conducting the fluidfor house or other lighting. At the side of the reservoir 6 near itsupper end, is a filling plug 28, slightly below the valve 12, in orderthat the reservoir may not be filled beyond this point, and the valvewill be above the oil surface at all times.

The operation of the device is as follows: The cook 26 having beenclosed, the reservoir 6 is filled through the filling plug 28 until theoil rises to within a short distance of the cock 12 The cook 24 is thenclosed and the pump 11 operated until the pressure gage 7 indicates thedesired pressure in the reservoir. The cock 12 is then closed, whichleaves the tank in condition to supply the oil or gaso lene to thehollow wires 23 and 27 under pressure. To light the lamp 9, the cook 24is o ened and the oil is forced, by reason of t e pressure aboveit,through the pipe 8 into the tank 16. When the gage 7 mdicates asufficient supply of fuel, the cook 24 is closed; then, by opening thecook 20 and heating the nozzle 19, the lamp 9 can be lighted and willburn until the fuel in the tank 16 is exhausted.

It will be seen, that the tank 16, may have a capacity for holdingliquid, sufiicient to maintain a light in the lamp 9, a predeterminedlen th of time, which is very advantageous in ighting streets and publicplaces, as it dis enses with the necessity for manual extinguishment ofthe light when it is not needed.

It is not my intention to limit the invention to the exact details ofconstruction hereinbefore described, but consider that I am entitled tosuch modifications as fall within a fair interpretation of the claims.

Having thus described my invention I claim as new and desire to secureby Letters Patent:

1. In a lamp, a su orting stand, a long tank or reservoir slida ymounted therein, a pressure gage and filling plug connected to thereservoir, a hand pump carried in a casing at the upper end of thereservoir, a hooked arm extending from the upper end of the reservoir, alamp and a small feed tank suspended from the arm, a gage carried by thefeed tank, a hollow wire extending from the feed tank to the reservoir,a second hollow Wire extending from the feed tank to a nozzle, and meansin front of the nozzle for con ducting fuel to the lamp.

2. The combination of a supporting stand adapted to receive the lowerend of a long main tank and hold it in an upright position, forming alamp post, a small feed tank supported above the main tank, a lampconnected to the feed tank, a feed pipe leading from the feed tank tothe main tank and passing through and below the bottom of the main tank,and means for forcing air above the free surface of the fuel containedin the main tank.

3. The combination of a long main tank forming substantially the entirelength of a lamp post, a small feed tank sup orted above the main tank,a supply pipe eading from the bottom of the mam tank, a hollow wireleading from the feed tank to the main tank and passing through the maintank below the bottom of the same and into said feed pipe, a lamp, meansconnecting the feed-tank with the lamp, and means for forcing air intothe main tank above the free surface of the fuel contained therein. e

4. The combination of a lon cylindrical main tank forming substantiallythe entire length of a lamp post, a feed tank supported a lamp supportedby the reservoir, a gage on the reservoir, a pump connected to thereservoir adapted to force air above the free surface of the fueltherein, a small feed tank and a lamp, a hollow wire leading from thefeed tank through and below the bottom of the reservoir, and meansconnecting the feed tank with the lamp.

6. The combination with a supporting stand, a reservoir held uprighttherein, a

casing secured to the reservoir, a fpump in the i casing, a hooked armprojecting om the upper end of the reservoir, a lamp and a feed tank susended from the arm, means for supplying tl fe feed tank from thereservoir, and meens for supplying the lamp from the feed tan i.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM SPENCER RYAN.
